You were feeling upset about failing your midterm and how your parents were going to be mad so you were ranting to Donatello about it. Like you would normally do before.. before the whole Kendra kidnapping Donnie thing. Donnie had always been a friend to you, like a little brother. So you were extremely confused and shocked when Donnie suddenly leaned forward and kissed you for a moment, just on the lips. With a shaky smile and nervous expression he starts to speak

“I-I.. you were sad and I-I wanted you n-not to be. N-no please don’t cry! Did I- Did I do something wrong? What did I do?” Donnie asks quickly as he sees you start to cry, tears welling up in his eyes as well

“Kendra always said that touching could m-make both of us feel good! Y-you’re not liking it and- and I didn’t like it at first but I won’t do it again! I promise!!” He says frantically, shaking as he takes a step back
